Get ready to hear a screeching noise in the subway you may not have heard in a while.

The alarms on some emergency exit door are making a comeback.

MTA officials say alarms have been reactivated at 10 subway stops, under a pilot program requested by the NYPD.

It comes as the MTA says it is losing millions of dollars with people using the doors to beat the fare.

The MTA turned the alarms off in 2014, after riders complained about the noise.

The agency hasn't specified which stations are getting the alarms back, but says it will have an update on the program in the coming weeks.
